Unformatted text preview: a . or E < 0, k i is imaginary, and B/A is xed by the condition that u = AJ i ( ir ) + BJ-i ( ir ) K i ( r ) is exponentially damped at large r , so the matching condition gives the energy quantization condition. q 2 + 1 / 4 cot q 2 + 1 / 4-1 / 2 = cot[ ln( a/ 2)- ( )] . We have immediately from the scaling periodicity that if is a solution so is n = e-n/ , where n is any positive or negative integer. In particular there are discrete energy levels extending to- . Of course with N nite the above solution breaks down for n -N and then one has to go back to the unsimplied matching condition to obtain the quantization condition. * E-mail address: firstname.lastname@example.org 1...
